But as we all know, wooden decks are notorious for becoming treacherously slippy. Especially when it’s been exposed to a long, dark, wet winter the build up of algae can simulate an ‘ice rink‘ and you probably dare not even walk on it.
WHY Decking Cleaning CAN'T WAIT
Because a green, slippery deck is a problem that gets worse every season you leave it.
Grey, blotchy boards and streaks of green algae drag down everything around them: patio, planting, view from your kitchen window. The deck that was meant to be the centrepiece of your garden quietly becomes the part you'd rather guests didn't notice.

Algae and mildew form a slick, almost invisible film on wet timber. One careless step on a damp morning carrying a tray, chasing a toddler, letting the dog out and someone goes down hard. It's usually the moment people finally pick up the phone.
Safe Underfoot Again - Same Day
You can't check a board for soft spots, loose fixings or splitting when it's buried under a layer of grime. A thorough clean reveals the true condition of the timber. So small repairs stay small, instead of being discovered the hard way.
Honest, No-Pressure Advice
Algae and moss hold moisture against the wood for months on end. Damp timber invites mould, fungi and wet rot. Once boards go soft, there's no cleaning your way back. The only fix at that stage is new timber, at many times the cost of a clean.
Non-Caustic, Biodegradable Treatment
But you may say –
I jet-washed it myself last spring
And look – by autumn it was green and slippery all over again.
If continually left unmaintained parts of the deck will even rot and an unsuspecting visitor can end up putting there foot right though the rotten wood. Leaving them injured and you embarrassed.
Do not let it get to this stage!!
If it has then you will need to replace some or all of the timber. Cedar, pine, birch, oak, hardwood, softwood – they all are commonly used in the UK. They ALL NEED maintaining. Cleaning is a vitally important part of this.
We can pressure wash away the dirt, grime and slime, this will produce a massive improvement. But we’re not finished – we then apply a treatment to remove the biological growth living on the wood.
This will produce the excellent results that you need. The high purity biocide soaks into the wood and gives lasting protection against instant regrowth. With regular re treatment you will notice the wood will last much longer as the product also acts as preservative – fighting off mould, fungi, wet and dry rot.
Your deck should be where summer happens: barbecues, morning coffee, bare feet and long evenings. We clean, treat and protect timber decking of every type, restoring colour and grip without harsh chemicals or heavy-handed jet washing that scars the wood.
A slippery terrace is a liability. We deliver fully documented, out-of-hours decking maintenance for pubs, restaurants, hotels, holiday parks, schools, care homes and managed apartment blocks – keeping outdoor spaces safe, compliant and open for business.

KEY COVERAGE Areas:
Not when it’s done properly. Timber is far softer than stone or paving. An aggressive jet wash the kind you’d hire from a DIY shop can furr the surface, gouge the grain and strip years of life from the boards.
We use controlled pressure matched to your timber, combined with a non-caustic, non-bleaching, biodegradable treatment that does the hard work chemically rather than by force. The result is clean, smooth, even finish.
Yes. PureGem is run by Luke and Gemma Lawrence, a husband-and-wife partnership with over twenty years in exterior cleaning. We hold the relevant training and certifications for the equipment and treatments we use.
We’re fully insured for both domestic and commercial work, and we’re happy to provide documentation on request.
For most decks in Yorkshire, a professional clean and biocide treatment every 12 to 24 months keeps the timber safe, attractive and protected.
Yes.
Once the timber is clean and dry we can apply a protective decking oil, stain or sealer in the finish of your choice. Where an old finish is flaking or patchy, we can strip it back first so the new coat goes on evenly.
A top coat isn’t always essential straight after a clean, and we’ll tell you honestly whether your deck actually needs one.
Yes.
The product we use is non-caustic, non-bleaching and biodegradable.
We take care to protect surrounding planting and rinse adjacent areas as we go. We simply ask that you keep children and pets off the deck until it has fully dried.
Most residential decks are cleaned and treated in a single visit. Typically half a day to a full day depending on size and condition.
You can usually walk on the deck once it’s dry, often the same day. If we’re applying an oil or stain, we’ll tell you the curing time for your chosen finish before we start.
